WE Apache barrel replacement

[Tank423]

Hi guys

 

Attempting to change barrel on my Apache tonight and have come across an issue no one else seems to have raised in the searching I've done.

 

The original barrel has 2 locating notches but all replacement barrels I've seen including the raved about crazy jet are all single notch, so are people filling down the second notch for barrels to fit? 

 

Am I missing something glaringly obvious?

 

Thanks

The crazy jets are not single notch , IIRC they actually have 3

I filed down the 2nd notch on my hop unit in my WE Scar H to fit a crazy jet. 

Figured I’d rather (potentially) ruin a £10 hop unit rather than a £30 barrel. It is easier as you know exactly how much material to remove in the hop unit and can test fit as you go. 
 

10mins dremeling and it was sorted, barrel is still securely held without the second notch
